I only use them for the occasional homework daatbase I haven't even tried to master them. I have seats at a theater, the seats are divided into 4 main areas A, B, C, D.

Each area shoud the same number ho rows and the same number what is the meaning of knock on effect seats ho row. Now, I don't yet know how many tables should a database have What does mean in math sets do my selects, but what I want to ask: If I do it this way, will my selects sould doable? I want to, for example, select an exact position within the theater where I know the area, row and seat number.

Would the 4 tables be a hindrance? Could you give an example of how such a "select" might look? This is my first time at the site, if the question does not belong here, please direct me to a more suitable site within stack exchange. Let's say datahase are 5 rows in every area, and 6 seats in every row. You'd want to use something along these lines. To use a table like this to model seat reservations, populate it with every possible area, row, and seat.

Then set a foreign key shou,d to it. By default, SQL Server will create a clustered index for a primary key constraint. You'll want to give careful datanase to the order of columns in your primary key constraints, how many tables should a database have consider adding other indexes as well. Especially since your outputs will often need to be ordered by area, row, and seat. If the information for the seat entity is the same per area, then you could simplify the design by having just one Seats table with an Area column.

You might find depending on what data access and UI technology that you're using that working with a surrogate primary key is easier, and just add a unique constraint on the AreaRowand Number combination. This way you wouldn't need to write complex queries and if another Area was added, then you only need to add a record to the Areas table, and not a new table. It's really worth thinking about the types of query you are going to want to run over your data, and the structure of the rest of your database - hae will almost certainly help you think through the model.

For instance, you're likely to want to link your seats to tickets when you sell a how many tables should a database have for a performance. That suggests you have a table called "performance", and another table called "ticket". Consider the structure of "ticket" - you want to link it to the seat. In your current design, the foreign key from "ticket" to "seat" is ugly - you'd need four columns to store this, and you can't guarantee that the ticket wouldn't have links to two seats if there's a bug somewhere.

You're also likely to want to find out how many free seats you have for a performance - again, your current design would need to query 4 tables, whereas the alternative just requires a single query. Finally, if you ever want to change the way you structure "seats" - for instance by adding a "default price" column, your current dominant person meaning in english needs you to make that change in 4 places; using a single table with an "area" foreign key allows you to make that change just once.
